adding folders to media share - DirecTV

When I go into the media share menu option, I see that it is pulling photos from my computer under: "This PC/Pictures". I have a few subfolders under there and whatever pictures are in those subfolders can be viewed on my TV. But I have my pictures elsewhere on my computer, so I tried to add a shortcut under that folder to where all my pictures are at, but the media share menu can't seem to locate the folder. I tried resetting the DirecTV box but that didn't work. I even tried creating a new folder under there that isn't a shortcut, but media share doesn't seem to find those either. How do I add new folders to the "This PC/Pictures" folder so that media share can locate it?
